Some symbols are used to represent more than one type of entity, and some
symbols are used to represent entities in more than one category. The "@"
symbol (by default) is used to represent the character.

It will not be necessary to remember all of the symbols and their meanings.
The "slash" command ("/") will identify any character appearing on your map.

Note that you can use a "user pref file" to change any of these symbols to
something you are more comfortable with.
